match the following
a. pivot joint i. shark
b. hinge joint ii.crab
c. ball and socket joint iii.elbow
d. exoskeleton iv.shoulder
e. cartilaginous body v.skull resting on the vertebral column ​

Answer 1

The correct matching has been given in a tabular form:

$\begin{array}{| c | c |}\cline{1-2} Pivot\: Joint & Skull\:on\:vertebrae \\\cline{1-2} Hinge\:Joint & Elbow \\\cline{1-2}Ball\:and\:Socket Joint & Shoulder \\\cline{1-2} Exoskeleton & Crab \\\cline{1-2} Cartilaginous\:Body & Shark \\\cline{1-2}\end{array}$

• Skull bones attached to the Atlas rotates on the axis provided by the Axis bone. Hence, it's a pivot joint.

• Elbow joint movement resembles a door opening/closing of a door on a hinge. Hence, called Hinge joint.

• Shoulder joint can move 360° in all directions, hence called ball and socket joint.
